It is impossible to enjoy idling thoroughly unless one has plenty of work to do. There is no fun in doing nothing when you have nothing to do. Wasting time is merely an occupation then, and a most exhausting one. Idleness, like kisses, to be sweet must be stolen. - Jerome K. Jerome

It’s hard to overstate the importance of this law to the Internet’s evolution. Without this law, all Internet content probably would be subject to a notice-and-takedown regime like we have for copyright law (see discussion about the DMCA Online Safe Harbors below). If websites had to remove user content upon notice to avoid liability, they would act conservatively, quickly pulling down complained-about content without much fuss. So, any company unhappy with negative consumer comments could simply contact the web host, claim that the comments were defamatory (making the web host potentially liable for the content), and expect the web host to scramble to take down the user’s comment.

47 USC 230 eliminates the notice-and-takedown option for people and companies trying to escape accountability. As a result, 47 USC 230 is a big part of the reason why the Internet became such a massive success.”
